IMPRGVEMENJ' IN EMBROIDERING'ATTACHMENTS FOR SEWING-MACHINES.

I Specification forming part of Letters Patent No. 154,088, dated August 11, 1874 application filed April 20, 1874.

] To all .whom 'it may concern:

Beit known that I, REUBEN M. ROSE, of

` Williamsburg, in the city of Brooklyn, in the countyv of Kings and State of New York, have invented certain Improvements in EmbroideringAttachments to Sewing-Machines, of which the following is a specification:

' This invention, as with the one for which Letters 4Patent No. 148,761 were issued to me -March=17, 1874, relates to embroidering attachments `for sewing-machines that operate and the embroidery-stitch produced consisting of iasuccession of coils, which the sewingthread 1s made to interlace. To this end I employ, as used 1n my previous invention, hereinbefor'e referred to, and others for the same purpose, a presser-foot attachment, which may be appliedto any ordinary sewing-machine in place of the usual foot, and has combined with ita horizontally-reciprocatin g needle for workingfthe embroidery-thread, which is required to pass rst in front ofthe sewing-needle and afterward back of the latter during its ascent, or across the path of said needle, and subsequently in frontof the sewing-needle again, to form a loop for the sewing-needle with its thread to pass through.

My invention consists, first, in an embroidery-needle having only a reciprocating motion in line with the feed, and formed with an inoline or curve at its 4forward end, onits rear side, immediately in advance of the eye of said needle, for operation in connection with an elastic sewing-needle, which the incline or curve of the embroidery-needle pushes back or to one side when required to pass in front of the sewing-needle, the latter afterward springing or being sprung forward to pass through the loop ofthe embroidery-thread. By this construction and combination of parts I dispense with any lateral movement of the embroidery-needle, thus simplifying the same and giving it a steadier and more reliable action generally. The invention also consists in a novel slotted construction of that portion of the presser-foot plate through which the sewing-needle passes for action in concert with the feed and horizontally-reciprocating emvantageous in cases where it is required` to make sharpfangular turns of the embroidery stitch or pattern.

In the accompanying drawing, Figure 1 represents a front elevation of my improved embroidery-thread attachment in relation with the sewing-needle during the ascent of the latter and forward motion of the embroidery-needle, and showing the sewing-needle as pushed back or to one side by the other needle; Fig. 2, a side view of like parts in the same relative positions; and Fig. 3, a plan thereof under similar conditions. Fig. 4 is a similar View to Fig. 2, but representing the sewingneedle as sprung forward in front of the embroidery-needle, and in the act of making its Vdescent through the loop left by the embroidery-needle as the latter makes its back stroke. Fig. 5 isa plan of the front portion of the presser-foot plate in illustration of its slotted construction to effect the spreading ofthe loop Fig. 6, a similar view with the embroideryneedle at the extremity of its forward stroke, and with the sewing-needle as making its descent, but before it is sprung forward, as shown in Fig. 4, by coming in contact with the ernbroidery-needle; Fig. 7, a like view of same devices, but showing the embroidery-needle at the end of its back stroke and the sewing-needle just before it leaves the loop. Fig. 8 is a top view of a piece of fabric with the embroidery-'stitch as produced thereon.

A is the bearing-plate or shoe of the presserfoot, provided on its upper surface with a horizontal slide, B, reciprocating in the line of feed within ways b b. C is the bed or table ofthe sewing-machine, and D the material to be embroidered. The slide B has attached to it in the rear, at c, a stout horizontal needle, E, for working the embroidery-thread d. This needle, the axial line of which intersects that of the sewing-needle F, or thereabout, has its eye near its forward end, and is bent or shaped on its rear side in advance of said eye to form an incline or curve, c, so that, in the forward motion of the slide B, the incline or curve c, coming in contact with the front of the sewing-needle F while the latter, having left the cloth, is passed upward, springs the sewingneedle (which is made elastic) backward, all as represented in Figs. 1,2, and 3 of the drawing. In this way the embroidery-thread d is projected in front of the sewing-needle, which latter, as soon as it rises above the embroidery-needle, springs forward by its natural elasticity to its normal position, as shown in Fig. 6, and which, in its next descent, is further temporarily sprung forward by coming in contact with the front side of the embroidery-needle E in the early portion of the back stroke of the latter, but immediately resumes its normal position again so soon as the embroideryneedle in its back stroke has passed it, the

y sewing-needle passing through the loop of the embroidery-thread and being coiled around the Asewing-needle as the embroidery-needle Vcompletes its descent, as represented in Fig.

7. The sewing-needle F, after the usual dwell yfor the passage of the shuttle through the loop of its thread, then rises again, and

,the embroidery-needle advances to repeat the operation, as before, the feed of the material takingplace at the concluding portion of the ascent of the sewing-needle, or in the early portion of its descent-that is, when wholly above the embroidery needle. Such feed draws the previous embroiderythread.(which has been last penetrated by the sewing-needle and its thread) tight, and each forward stroke of the embroidery needle carries new thread beyond the sewing-needle to form a fresh loop, which is left by the embroidery-needle in its back stroke.

The embroidery-needle E or its operatingslide B may be worked in timely relation with the sewing-needle by means of a bell-crank, G, and link H direct from the sewing-needle bar, and said needle, if desired, be steadied in its action, at or near its working-point, by a screw, k, or other-suitable support or guide.

The two'threads d and f are arranged to interlace within a wide or enlarged slot in the forward portion of the presser-foot plate A, so as to receive the loop left by the embroiderythread needle within it, and so that said loop is spread and retained open for the sewingneedle to pass through, and is afterward tightened and drawn into'line, which is in advance of the sewing-needle, by means of a curved or inclined back end, fi, of the slot h, along` which incline i the thread of the loop is guided toward thefront of the machine by the feed of the material under the presser-foot each successive stitch, the ordinary or any suitable feeding mechanism being used. This construction of the presser-foot .or its plate will be found of great service in making sharp angular turns of the embroidery `stitch or pattern.

I claim- 1. The .horizontally-.reciprocating embroidery-needle E, formed .with v a curved or inclined surface, e, on its -rear side at Yits forward'end, near the eye thereof, in combination .with .an elastic eye-pointed sewing-needle, F, Asubstantially as specified.

l2. The presser-foot shoeor plate A, `constructed with a slot, h, having .a curved inclined back end, i, in combination withan embroidery-needle and a sewing-needle, operating to inter-lace their threads, as described, the whole being arranged for operation in connection with the feed, essentially as herein lset forth.

3. rlhe combination of the screw-support and guide k with the horizontally-reciprocating embroidery-needle E, for operation in relation with lthe sewing-needle, substantially as specified.
